G Sudeep, M Vijayakumar Naik, Y Pavani, D VenkatabramhaNaidu 02 02 Interior Permanent Magnet Synchronous Motors IPMSMs are widely adopted in electric vehicle EV propulsion systems due to their high efficiency and torque density However torque ripple remains a significant challenge particularly under dynamic load conditions affecting drivability efficiency and component lifespan This study presents a comparative analysis of two prominent control strategiesFieldOriented Control FOC and Direct Torque Control DTC in terms of their effectiveness in reducing torque ripple in IPMSM drives A simulation framework was developed using Python to model the motor behaviour under identical speed and load conditions The results indicate that FOC produces smoother torque output with minimal ripple owing to its decoupled control of flux and torque through dqaxis currents In contrast DTC despite offering faster dynamic response introduces higher torque ripple due to its hysteresisbased voltage vector switching Quantitative comparisons based on torque ripple amplitude current quality and speed regulation confirm the superiority of FOC for applications where smooth and efficient torque delivery is critical This research reinforces FOC as the preferred control strategy for IPMSMdriven EVs especially in scenarios demanding high precision and minimal mechanical stress Copyright (c) Journal of Science Engineering Technology and Management Science.
